escape character over ws

[mzi1sk]

If I send this command to json server using websocket I am getting error : err:invalid character '\x1b' in string literal. If I send command using localhost:8989 it works. As for my device is escape character(\x1b ) a must symbol any idea what I do wrong is appreciated.

sendjson {"Data":[{"D":"\u001bb\r\n","ID":"100","Pause":100},{"D":"Nazov Pocet Jedn.Cena Dan Suma \r\n","ID":"101","Pause":100},{"D":"Aglio olio e peperoncino \r\n","ID":"102","Pause":100},{"D":" 1 Ks 7.5 \u001b1 7,50 EUR \r\n","ID":"103","Pause":100},{"D":"Pasta salmone zucchine \r\n","ID":"104","Pause":100},{"D":" 1 Ks 11.0 \u001b1 11,00 EUR \r\n","ID":"105","Pause":100},{"D":"Aglio olio e peperoncino \r\n","ID":"106","Pause":100},{"D":" 1 Ks 7.5 \u001b1 7,50 EUR \r\n","ID":"107","Pause":100},{"D":"Pasta salmone zucchine \r\n","ID":"108","Pause":100},{"D":" 1 Ks 11.0 \u001b1 11,00 EUR \r\n","ID":"109","Pause":100},{"D":"Linguine frutti di mare \r\n","ID":"110","Pause":100},{"D":" 1 Ks 11.0 \u001b1 11,00 EUR \r\n","ID":"111","Pause":100},{"D":"\u001bk 48,00 \r\n","ID":"112","Pause":100},{"D":"\u001bP1 48,00 EUR \r\n","ID":"113","Pause":100},{"D":"\u001be \r\n","ID":"114","Pause":100}],"P":"COM3"}

and here is my simple websocket.js

function senddocument( message) {
timeoutID = window.setTimeout(senddocument2ws, 200,message);
}

function senddocument2ws( message) {
window.socket.send(message);
}

function opensocket(address) {
window.socket = new WebSocket(address);
window.socket.onopen = function() {
console.log('open');
}
window.socket.onerror=window.socket.onclose = function (errorEvent) {
alert("Spojenie s fiskalnou pokladnou je uzavrete!!");
}

window.socket.onmessage = function(msg) {
    console.log('receive');
    console.log(msg);
}

}

function closesocket() {

window.socket.close();

}

Thank you

I'm not really sure what you're asking? You're saying it works from
localhost:8989 so there's no error.

yes exactly. From localhost it runs perfect. If I try to send it over ws, I get :

This forum is for bugs, not to help you figure out how to write code.

ok isnt it an issue?
if I submit json from localhost:8989 and it works, but if I use websocket and send very same json over there it will not work. As I think problem is on json server side. When it receives escape format "\u001b" it converts it to � aka '\x1b' that jsonserver is not able to process ?

Anyway is there any other forum to the project ? Maybe you can consider to set one, as that would really help to avoid your waste of time with us not smart enough to get over some probably stupid mistakes.

localhost?:8989 is over Websockets. so if it works there, it works over Websockets. so this is your code.

There's no forum but feel free to set one up.
